This seems to have been introduced in 57cc0d8 since the condition !atty::is(Stream::Stdin) was inverted to std::io::stdin().is_terminal(). This seems to be a mistake since the comment says

// If we are reading from stdin, only enable paging if we write to an
// interactive terminal and if we do not *read* from an interactive
// terminal.

but the current code enables paging if stdin is interactive.

This PR just flips the condition back to how it was to restore the original behavior.
No changelog update as there hasn't been a release since the regression was introduced.

Fixes #2572
